Advanced DNA testing using genealogy databases could take weeks or months to identify Nancy Guthrie's abductor after initial FBI database search failed.

DNA is the blueprint of life. Genes encode proteins and serve as the body's basic components. However, building a functioning organism also requires precise instructions about when, where, and how much those components should be produced.

The number of DNA profiles being studied and other details were not being released because of the active investigation, a sheriff's spokesperson said.

A DNA expert believes the kidnapper "will be identified” through investigative genetic genealogy after an unknown person's DNA was recovered at Nancy Guthrie's home.

For the first time, researchers have succeeded in developing an artificial DNA base pair that is based on a different chemical force than natural genetic material. While the common natural DNA building blocks are held together by hydrogen bonds,
